His main research interests are in the modeling, simulation, fabrication and characterization of photonic crystals in several semiconductors. His team at the C2N laboratory has recognized expertise in the fabrication, and characterization of linear and nonlinear properties of photonic crystal components based on silicon. In 2009, he obtained one of the two Chairs University Paris-Sud/CEA and started to develop the processing of photonic crystals in diamond at C2N in collaboration with CEA-LIST.
